ABSTRACT

Containers are provided for use with a beverage dispensing device. The container can include a housing defining a hollow interior and having an opening leading to the hollow interior, a cover coupled disposed over the opening, an inlet leading to the hollow interior, and an outlet spaced apart from the interior. The inlet and outlet can each have valves movable between open and closed positions for allowing fluid flow into and out of the hollow interior.

FIELD

Additive containers for use with beverage dispensing devices are provided.

BACKGROUND

Conventional beverage dispensing devices operate to carbonate and/or flavor water. Some devices may mix carbonated water and a flavoring compound together in a machine and then dispense the resulting mixture into a receptacle. Unless the devices are thoroughly cleaned, this method can result in contamination occurring over time. Other devices rely on crushing, puncturing, and/or generally compromising flavoring containers in order to access the flavoring compounds inside. These methods of breaching flavoring containers can result in splatter and mess, which, if not thoroughly cleaned, can result in similar contamination.

Still other devices rely on carbonating water within a specialized container to be attached to the device, and from which the resulting beverage is served. The container can be pre-filled with water and/or flavoring, and then it can be secured to the devices and pressurized within the container and used to serve the resulting beverage. These devices, however, can create excess plastic waste, as specially adapted bottles must be produced to interface with the device.

Accordingly, there remains a need for improved methods and devices for preparing a beverage containing an additive.

SUMMARY

Additive containers for use with beverage dispensing systems are provided. Related apparatuses and methods are also provided.

In an embodiment, an additive container is provided. The additive container can include a housing defining a hollow interior configured to retain a fluid therein, and an elongate tube disposed within the housing. The housing can have an inlet leading to the hollow interior and an outlet leading to the hollow interior. The inlet and the outlet can be spaced apart from one another. The additive container can also include an elongate tube disposed within the housing and having a first end fluidly coupled to the inlet and a second end defining an opening. The second end can be positioned at an opposite end of the housing from the first end, and the second end can be configured to extend above a level of fluid in the housing to allow gas to flow through the tube and into the housing. The additive container can further include a valve disposed in the outlet and movable between a closed configuration in which fluid is prevented from flowing therethrough, and an open configuration in which fluid within the hollow interior can flow therethrough. The valve can be configure to move from the closed position to the open position in response to a pressure increase in the hollow interior resulting from delivery of gas into the hollow interior through the tube.

The additive container can vary in a number of ways. For example, the inlet can include a collar extending therearound and projecting from the housing. For example, the inlet and outlet can be positioned in a first end of the housing. The second end of the tube can be positioned adjacent a second end of the housing opposite the first end. For example, the second end of the tube can be configured to be positioned above a level of fluid in the housing is oriented such that the inlet and outlet are positioned below the tube. For example, the housing can include a body defining the hollow interior and a cap disposed over an opening in the body leading to the hollow interior. In some aspects, inlet and outlet can be in the cap. For example, the inlet and the outlet each can have a central longitudinal axis extending substantially parallel to one another.

In another embodiment, an additive container is provided. The additive container can include a housing defining a hollow interior, an inlet positioned in the bottom of the housing, and an outlet positioned in the bottom of the housing. The housing can have a top, a bottom, and at least one sidewall extending between the top and bottom. The inlet can have a tube extending therefrom into the hollow interior toward the top of the housing. The tube can have an open end adjacent the top of the housing, and the tube can be configured to allow a gas to be passed into the inlet and through the tube for delivery into the hollow interior. The outlet can have a valve disposed therein. The valve can be configured to move from a closed position to an open position in response to a pressure increase in the hollow interior.

The additive container can vary in a number of ways. For example, the housing can include a body and a cap coupled to the body. The cap can have the inlet and outlet therein. In some aspects, the body can be rigid and non-deformable. For example, inlet can include a collar disposed therearound and projecting from the housing. For example, the outer valve can include a slit valve. For example, the inlet and outlet can be spaced a distance apart.

In another embodiment, an additive container is provided. The additive container can include a housing defining a hollow interior and having an opening at a first end leading to the hollow interior, a cover disposed over the opening, an inlet formed in a wall of the housing and leading to the hollow interior, and an outlet formed in the wall of the housing and spaced apart from the inlet. The inlet can have an inlet valve movable between open and closed positions for allowing fluid flow into the hollow interior. The outlet can have an outlet valve movable between open and closed positions for allowing fluid flow out of the hollow interior.

The additive container can vary in a number of ways. For example, the cover can define a first end of the housing and the inlet and outlet are formed in a second end of the housing opposite the first end. For example, the cover can be pivotally coupled to the housing. For example, the cover can be removably coupled to the housing. For example, the cover can prevent fluid flow into and out of the hollow interior through the opening when the cover is disposed over the opening.

In another embodiment, an additive container is provided. The additive container can include a housing defining a hollow interior and including an opening at a first end leading to the hollow interior, and a cap coupled to the housing and configured to close off the opening. The housing can include an inlet and an outlet formed in wall of the housing at a second end opposite the first end. The inlet and outlet can be in fluid communication with the hollow interior and at least one of the inlet and outlet including a valve therein.

The additive container can vary in a number of ways. For example, the inlet can include an inlet valve and the outlet includes an outlet valve, the inlet valve and the outlet valve being respectively movable between open and closed positions to allow fluid flow therethrough. For example, the cap can be removably coupled to the housing. For example, the housing can have a substantially ovular cross-section with major and minor axes, and wherein the inlet and the outlet are aligned along the minor axis. For example, the cap can be configured to couple to the housing via a snap-fit. For example, the cap can be configured to seal the hollow interior when coupled to the housing. For example, the cap can be pivotally coupled to the housing.

In another embodiment, an adapter is provided. The adapter can include an adapter base having upper and lower surfaces with first and second fluid ports therein, a first connector positioned in the first port on the upper surface and having a first valve therein, a second connector positioned in the second port on the upper surface and having a second valve therein, and at least one anchor extending from the lower surface of the adapter base and configured to secure the adapter base to a beverage dispenser. The first valve can be configured to allow a first fluid to flow therethrough in a first direction, and the second valve can be configured to allow a second fluid to flow therethrough in a second direction that is opposite the first direction.

The adapter can vary in a number of ways. For example, the adapter can further include a first tubing coupled to the first port, and a second tubing coupled to the second port. In some variations, the adapter can further include a housing coupled to the first tubing and the second tubing. The housing can be configured to receive the first fluid from the first tubing and configured to dispense the second fluid to the second tubing. For example, the first and second connectors can each include a hollow tube having a flared portion at a terminal end thereof. For example, the first and second ports can define a substantially figure-8 shaped contour around a perimeter thereof. For example, the adapter base can be substantially triangular. For example, the first fluid port can include a first valve movable between open and closed positions to allow the first fluid therethrough, and the second fluid port can include a second valve movable between open and closed positions for allowing the second fluid therethrough.

In another embodiment, a device is provided. The device can include a housing defining a hollow interior, an adapter configured to couple with a beverage dispenser, a first fluid pathway disposed between the housing and the adapter, and a second fluid pathway disposed between the housing and the adapter. The first fluid pathway can be configured to transport at least one gas from the adapter to the housing. The second fluid pathway can be configured to transport an additive from the housing to the adapter in response to the at least one gas being transported from the adapter to the housing.

The device can vary in a number of ways. For example, the first fluid pathway and second fluid pathway can include flexible tubing. For example, the adapter can include an inlet port and an outlet port, and wherein the first fluid pathway is coupled to the inlet port and the second fluid pathway is coupled to the outlet port. In some variations, the inlet port can include an inlet valve movable between open and closed positions, and the outlet port comprises an outlet valve movable between open and closed positions. For example, the adapter can include at least one anchor extending from a first side thereof and configured to secure the adapter to the beverage dispenser, and the first fluid pathway and second fluid pathway can couple to a second side of the adapter opposite the first side. In some variations, the at least one anchor can include a first anchor disposed on a first end of the adapter and a second anchor disposed on a second end of the adapter. For example, the adapter can be substantially triangular.

DETAILED DESCRIPTION

Certain illustrative embodiments will now be described to provide an overall understanding of the principles of the structure, function, manufacture, and use of the devices and methods disclosed herein. One or more examples of these embodiments are illustrated in the accompanying drawings. Those skilled in the art will understand that the devices and methods specifically described herein and illustrated in the accompanying drawings are non-limiting illustrative embodiments and that the scope of the present invention is defined solely by the claims. The features illustrated or described in connection with one illustrative embodiment may be combined with the features of other embodiments. Such modifications and variations are intended to be included within the scope of the present invention.

Further, in the present disclosure, like-named components of the embodiments generally have similar features, and thus within a particular embodiment each feature of each like-named component is not necessarily fully elaborated upon. Additionally, to the extent that linear or circular dimensions are used in the description of the disclosed systems, devices, and methods, such dimensions are not intended to limit the types of shapes that can be used in conjunction with such systems, devices, and methods. A person skilled in the art will recognize that an equivalent to such linear and circular dimensions can easily be determined for any geometric shape.

In general, additive containers for use with beverage dispensers and carriages for receiving additive containers are provided. In one embodiment, an additive container is provided that can contain an additive for use in a beverage dispensing process. The additive container can have a housing having a hollow interior configured to retain a liquid therein. The housing can include an inlet and outlet configured to control the flow of fluid into and out of the hollow interior. In some embodiments, the inlet and/or the outlet can have a seal disposed therein that is configured to open in the presence of a pressure differential between an interior and an exterior of the additive container in an attempt to eliminate the pressure differential. In some embodiments, the inlet can have a snorkel tube that extends from the inlet into the hollow interior of the housing. The tube can be configured to deliver gas above a fluid level to allow a pressure with the housing to be increased. In other embodiments, the housing can has a cover disposed over an opening, and an inlet and outlet formed in a wall of the housing. In yet other embodiments, additive containers having a shape and design that corresponds to a carriage located on a beverage dispensing device are provided. The carriage can have complimentary features to receive and retain the additive container, and when retained, the additive container can be employed by a beverage dispensing device for use in the creation of customized beverages. In another embodiment, an adapter is provided that can form an interface between an additive container and a beverage dispensing system. The adapter can be configured to couple to a carriage and may be shaped and designed to correspond to the carriage. The additive container can include tubing configured to couple the container to the adapter. In other aspects, an additive container is provided having an enlarged interior volume.

Methods of dispensing an additive stored within the additive container can vary. In some embodiments, the additive container is pressurized with a gas, such as air, to cause the outlet to open and dispense the stored additive. When the additive container is properly seated and retained by a carriage, a gas line fluidly coupled to a pump can receive the inlet of the additive container or the inlet of the adapter in order to seal around the inlet in preparation for the introduction of gas into the additive container during a dispensing procedure. Gas can be pumped by the pump, though the gas line, through the inlet, and into the hollow interior of the additive container. The resulting increase in internal pressure can cause the outlet seal to open and dispense an amount of the additive proportional to the amount of gas introduced through the inlet.

Examples of beverage dispensing systems, additive containers, and associated methods beyond that which are described herein can be found in U.S. application Ser. No. 17/989,640, titled “Carbonation System Ingredient Container,” which is incorporated by reference in its entirety.

FIGS. 1-2 illustrate a beverage dispensing system 10 according to one embodiment. The beverage dispensing system 10 can be used to create and dispense customized beverages for a user, based on desired characteristics of the beverage. The illustrated beverage dispensing system 10 generally includes a housing 12 having a fluid reservoir 14 and a carbonation assembly 16. A carriage assembly 18 can be included on and/or coupled to the beverage dispensing system 10, and it can receive one or more additive containers and/or adapters (as described herein) to be used in the creation of beverages. The additive containers can include one or more additives (e.g., a flavorant, a vitamin, a food dye, etc.) to be included in a created beverage as desired.

During a beverage dispensing process, a user can actuate inputs located at a user interface 22 in order to select specific characteristics of the desired beverage, such as volume, carbonation level, specific additives, and additive amount. If the user selects inputs to indicate that the beverage is carbonated, water can be fed from the fluid reservoir 14 and into the carbonation assembly 16, and carbon-dioxide can be fed from a canister 24 and into the carbonation assembly 16 to produce carbonated water. If the user selects inputs to indicate that one or more additives should be added to the beverage, the beverage dispensing system 10 can dispense the additive from the one or more additive containers 20 coupled to the system. The beverage can be dispensed into a container, such as a drinking glass 26.

FIG. 3 illustrates one embodiment of a carriage assembly 100 which can be coupled to and/or retained with or within a beverage dispensing device, such as beverage dispensing device 10. In the illustrated embodiment, the carriage assembly 100 is contained within a carriage housing 100A. The carriage assembly 100 can include one or more carriages 120, which can each seat and retain one or more additive containers (see, e.g., FIGS. 4A-5B, 8A-8B) and/or adapters (see, e.g., FIGS. 6A-6F) for use in a beverage dispensing process as explained herein. Although the carriage assembly 100 is shown having two separately movable carriages 120, a different number of carriages 120 are contemplated herein as well. For example, the carriage assembly can be in the form of a single movable carriage having one or more cavities with each cavity configured to receive an additive container. Additive containers and their retention within the carriage assembly 100 will be described in greater detail below.

The carriages 120 may include at least one groove and/or protrusion that complements at least one protrusion and/or groove of an additive container or adapter. For example, as seen in FIG. 3 , a carriage 120 may include two bat-wing shaped protrusions 138 at least partially surrounding a substantially figure-8 shaped central recess 137. Although the carriages 120 are described and shown as having certain areas recessed and other areas protruding, carriages 120 with the opposite features are contemplated herein as well, i.e., one or more protrusions are recesses and one or more recesses are protrusions.

FIGS. 4A-4C illustrate an exemplary embodiment of an additive container 200. The illustrated additive container 200 generally includes a cap 210 coupled to a housing 250 which can be configured to contain an additive (e.g., a flavorant, a supplement, a vitamin, a coloring agent, etc.) to be used in the creation of beverages. The additive can be in the form of a fluid, a solid, a powder, a gel, a syrup, or any other form. The additive container 200 can come in a variety of sizes.

The additive container 200 can store the additive inside, and, as part of a beverage creation process, receive a measured volume of gas (e.g., air, carbon-dioxide, etc.) through an inlet 224 resulting in an increased internal pressure. The increase in internal pressure within the additive container 200 can result in an outlet 226 emitting a tailored amount of the additive as a consequence of eliminating or reducing the newly-created pressure differential across the outlet.

The illustrated housing 250 includes a base 250B, a sidewall 250S extending upwardly from the base, and a top 250T, which together can define an interior space to store the additive. The illustrated housing 250 has a generally oblong, ovular form similar to a race-track configuration, as seen in FIG. 4A. While the housing 250 is shown as having a specific form, the housing 250 can take on a variety of forms.

FIG. 4B depicts an embodiment of the cap 210 and elements thereof. The illustrated cap 210 has a substantially rounded triangular shape and includes a cap base 220 and a cap cover 240 coupled to the cap base 220 via, e.g., a living hinge. The cap cover 240 can be used to close an inlet and outlet discussed further below. The triangular shape can be defined by a perimeter having first, second, and third sides, with the first side being longer than each of the second and third sides. While the cap 210 is shown as having a specific form, the cap 210 can take on a variety of forms.

As indicated above, the cap 210 can include an inlet 224 and an outlet 226, as shown in FIG. 4B. The inlet 224 and outlet 226 can be spaced a distance apart from one another, and can be aligned with one another along an axis extending therethrough, with a central longitudinal axis of each of the inlet and outlet being parallel. In other embodiments, the inlet 224 and outlet 226 can be offset and unaligned relative to one another and/or can have central longitudinal axes that are non-parallel. In other embodiments, the inlet and outlet can be concentric and need not be spaced apart.

As seen in FIG. 4B, the inlet 224 can include an inlet collar 224A and the outlet 226 can include an outlet collar 226A, with the collars defining an opening within the inlet or outlet. Although the inlet collar 224A and the outlet collar 226A are shown in a circular form, the inlet and outlet collars 224A, 226A can take on a number of shapes, including various geometric shapes, e.g., a triangle, a star, etc., as well as fanciful and/or irregular shapes, e.g., a letter, a logo, etc. The form of the inlet and outlet collars 224A, 226A can be the same or different. Further, the inlet 224 and outlet 226 need not include collars, and instead can be in the form of openings formed in a wall of the cap.

As seen in FIG. 4B, the cap base 220 can further include a pair of shoulders 231 that extend upward from the cap base 220. Each shoulder 231 can have a shape that complements a shape of the carriage 120. Recesses 228 can flank each side of the inlet 224 and the outlet 226, and the recesses 228 can each be shaped to correspond to protrusions in a carriage (e.g., flanking protrusions 138 on carriage 120). For example, the recesses 228 can be shaped to follow an outer contour of the collars 224A, 226A and can take a “bat wing” form. In particular, similar to the flanking protrusions 138, the recesses 228 can have a radially outward sidewall that is concavely curved along its length and two inner sidewalls that are concavely curved to follow the contours of the inlet and outlet 224, 226. The recesses 228 can take on various other forms as well, and their form may be at least partially dependent upon the placement and form of other components on the cap 210 and/or the carriage. The recesses 228 can be placed a slight distance apart from the inlet 224 and the outlet 226, thus defining a central pattern 230 located in the space between the collars 224A, 226A and the recesses 228. As best seen in FIG. 4B, the central pattern 230 can take the form of a “figure-8,” however other forms may be present. The illustrated central pattern 230 is shown being flush with the upper surface of the base 220, however the central pattern 230 can protrude above the upper surface or can be recessed below the upper surface. The central pattern 230 can be a protrusion, a recession, or a combination thereof with a portion of the central pattern 230 protruding from the cap 210 and a portion of the central pattern 230 receding into the cap 210. In some variations, the inlet and outlet collars 224A, 226A can contribute to the central pattern 230.

As explained previously with respect to the carriage 120, although the cap base 220 is described and shown as having certain areas recessed and other areas protruding, cap bases with the opposite features are contemplated herein as well, e.g., all protrusions are recessed and all recesses are protrusions. Further, cap bases are also contemplated that may have only a portion of the features interchanged, such that only one or a few protrusions are recessed and/or only one or a few recesses are protrusions. Additionally, and as described in further detail below, cap bases are contemplated that may have fewer protrusions and/or recesses.

The outlet 226 can include an outlet valve 226D configured to open to dispense an additive therefrom during a beverage dispensing process. The outlet valve 226D can be configured to open when subjected to a high enough pressure differential, such as when gas is introduced to the hollow interior of the housing 250 via the inlet 224. One exemplary valve is a slit valve. Further details regarding the valve are disclosed in the aforementioned application incorporated by reference herein.

As seen in FIG. 4C, the inlet 224 may include an inlet tube 224E fluidly coupled thereto. As illustrated, the inlet tube 224E can extend from the inlet 224 into the hollow interior of the housing 250, extending toward a wall of the housing 250 opposite the inlet 224, e.g. the base 250B of the housing 250. The inlet tube 224E may be configured to terminate proximate to an interior wall of the housing 250 opposite the inlet 224, e.g. the base of the housing 250. The additive container 200 may be configured to couple to carriage 120 such that inlet tube 224E extends in an upward direction away from the carriage, with the base forming a top of the container and the inlet and outlet being positioned at a bottom of the container. Such configuration can allow an open end 225E of the inlet tube 224E to be positioned above a level of fluid F within the container, as shown. This allows gas to be introduced into the empty space within the container, while also preventing fluid in the container from flowing into the inlet tube 224E and out the inlet 224.

A person skilled in the art will appreciate that the inlet tube 224E can be coupled to the inlet 224 using a variety of techniques. For example, the inlet tube 224E may be removably mounted by friction fit or other known techniques on a projection extending into the housing 250 from the inlet 224. In other aspects, the inlet tube 224E can be integrally formed with the cap 210. In other aspects, the inlet tube 224E can be passed through the inlet 224 in the cap 210 and fixed thereto, e.g., by adhesive or welding. While various attachment techniques can be utilized, the inlet 224 and inlet tube 224E are preferably configured to couple to a gas outlet on a beverage dispensing system (e.g., beverage dispensing system 10) to allow gas to be pumped through the inlet tube 224E into the housing.

While not shown, to further prevent fluid flow into the inlet tube 224E during rotation of the container 200 to position the inlet 224 and outlet 226 in a downward orientation as shown in FIG. 4C, rather than the upward orientation shown in FIG. 4A, the inlet 224 and/or inlet tube 224E can include one or more one way valves therein. Such a valve can allow air to flow through the tube 224E and out the open end 225E, while preventing any air and/or fluid from flowing in the reverse direction.

As indicated above, in use the inlet tube 224E can be configured to introduce at least one gas to the interior of the housing 250 from a beverage dispensing system (e.g., beverage dispensing system 10) during a beverage dispensing process, and as a result of the introduction of the at least one gas, dispense an additive stored therein. This can be achieved by orienting the additive container 200 with the inlet 224 and outlet 226 facing downward and fluidly coupling the inlet 224 to a gas outlet on the beverage dispensing system. When air is pumped through the inlet 224 and inlet tube 224E it is delivered into the hollow interior at a location about the fluid, thereby creating pressure within the hollow interior. The pressure causes the fluid to apply a force to the outlet valve 226D, and once the force exceeds an opening or cracking pressure of the outlet valve 226D, the valve 226D will open and release fluid. An amount of gas dispensing into the container 200 can be controlled to thereby control an amount of fluid dispensed from the container 200.

FIGS. 5A and 5B depict another embodiment of an additive container 300 configured to contain an additive (e.g., a flavorant, a supplement, a vitamin, a coloring agent, etc.) to be used in the creation of beverages. The additive can be in the form of a fluid, a solid, a powder, a gel. a syrup, or any other form. The additive container 300 may come in a variety of sizes. The additive container 300 can store the additive inside, and, as part of a beverage creation process, receive a measured volume of gas (e.g., air, carbon-dioxide, etc.) through an inlet 324 resulting in an increased internal pressure. The increase in internal pressure within the additive container 300 can result in an outlet 326 emitting a tailored amount of the additive as a consequence of eliminating or reducing the newly-created pressure differential across the outlet.

As shown, the additive container 300 includes a housing 350 having a base 350B at a first end and a sidewall 350S extending upwardly from the base 350B to an interface 320 at a second end opposite the first end. The illustrated housing 350 has a generally oblong, ovular form similar to a race-track configuration, as seen in FIGS. 5A and 5B. While the housing 350 is shown as having a specific form, the housing 350 can take on a variety of forms.

The base 350B can include a cover or lid 310 extending across an opening in the first end of the housing 350. The lid 310 can be configured to provide access to the hollow interior to allow for fluid to be delivered into the housing 350. The illustrated lid 310 has a generally oblong, ovular form. The lid 310 can be coupled to the housing 350 to close the opening formed by housing 350 and close off and seal the hollow interior. The lid 310 can couple to the housing 350 via a snap-fit, a living hinge, or various other coupling mechanisms. The lid 310 can be pivotally coupled to the housing 350, or can be fully removable. While the lid 310 is shown as having a specific form, the lid 310 can take on a variety of forms.

As indicated above, the housing 350 can include an interface 320 at an opposite end from the base 350B. The interface 320 can be a portion of the housing 350 configured to be received within and interact with a carriage in a beverage dispensing apparatus. In the illustrated embodiment, the interface 320 is an integral portion of (e.g., monolithic with) the housing 350. The interface 320 can have a shape that corresponds to a shape of the carriage 120. The shape can vary based on the beverage dispensing system. As further shown, the interface 320 can include the inlet 324 and the outlet 326 therein. As seen in FIG. 5C, in the illustrated embodiment the inlet 324 includes an inlet collar 324A and the outlet 326 includes an outlet collar 326A, with the collars defining an opening within the inlet or outlet. Although the inlet collar 324A and the outlet collar 326A are shown in a circular form, the inlet and outlet collars 324A, 326A can take on a number of shapes, including various geometric shapes, e.g., a triangle, a star, etc., as well as fanciful and/or irregular shapes, e.g., a letter, a logo, etc. The form of the inlet and outlet collars 324A, 326A can be the same or different. Further, the inlet and the outlet need not include a collar and instead can be in the form of an opening formed in the end wall of the housing.

As seen in FIG. 5C, the interface 320 can further include a pair of shoulders 331 that extend upward from the interface 320. Each shoulder 331 can have a shape that complements a shape of carriage 120.

In some embodiments, recesses 328 can flank each side of the inlet 324 and the outlet 326, and the recesses 328 can each be shaped to correspond to protrusions in a carriage (e.g., protrusions 138 on carriage 120). For example, the recessed 328 can be shaped to follow an outer contour of the collars 324A, 326A and can take a “bat wing” form. In particular, similar to the protrusions 138, the recesses 328 can have a radially outward sidewall that is concavely curved along its length and two inner sidewalls that are concavely curved to follow the contours of the inlet and outlet 324, 326. The recesses 328 can take on various other forms as well, and their form may be at least partially dependent upon the placement and form of other components on interface 320. The recesses 328 can be placed a slight distance apart from the inlet 324 and the outlet 326, thus defining a central pattern 330 located in the space between the collars 324A, 326A and the recesses 328. As best seen in FIG. 5C, the central pattern 330 can take the form of a “figure-8,” however other forms may be present. The illustrated central pattern 330 is shown being flush with an upper surface of the interface 320, however the central pattern 330 can protrude above the upper surface or can be recessed below the upper surface. The central pattern 330 can be a protrusion, a recession, or a combination thereof with a portion of the central pattern 330 protruding from the interface 320 and a portion of the central pattern 330 receding into the interface 320. In some variations, the inlet and outlet collars 324A, 326A can contribute to the central pattern 330.

As explained previously with respect to the carriage 120, although the interface 320 is described and shown as having certain areas recessed and other areas protruding, bases of housings with the opposite features are contemplated herein as well, i.e., all protrusions are recessed and all recesses are protrusions. Further, bases of housings are also contemplated that may have only a portion of the features interchanged, such that only one or a few protrusions are recessed and/or only one or a few recesses are protrusions.

The outlet 326 may include an outlet valve 326D configured to open to dispense an additive therefrom during a beverage dispensing process. The outlet valve 326D can be configured to open when subjected to a high enough pressure differential, such as when gas is introduced to the hollow interior of the housing 350 via inlet 324. As seen in FIG. 5C, the inlet 324 can also include an inlet valve 324D configured to introduce a gas to the interior of the housing 350 during a beverage dispensing process.

In use, the interface 320 of the housing can be positioned facing downward, such that the inlet 324D and outlet 326D are oriented downward and the base 350B is positioned at the opposite end and is oriented upward. The interface 320 can be received within a carriage to couple the inlet 324D to a gas pump for delivering gas into the housing. The lid 310 can be sealed with respect to the housing to allow a pressure within the housing to be maintained. Gas can thus be pumped into the housing through the inlet to increase the pressure, and thereby cause fluid in the housing to be dispensed by the outlet, as previously described with respect to other embodiments herein.

In yet another embodiment, rather than having valves located on or formed as part of the ingredient container, an adapter can be provided that can be used to couple an ingredient container to a beverage dispensing system. FIGS. 6A-6F illustrate one embodiment of an adapter system that can function as an interface between a beverage dispensing system 10 and a container. The adapter 400 can be configured to couple with the carriage 120 in order to facilitate the dispensing of an additive stored in a container 470 that is separate from the carriage 120, as will be described in greater detail below. Use of the adapter 400 allows connection of almost any size external container 470 without constraint. While not shown, in other embodiments the adapter can be configured to function as a lid on a container, or it can be configured to directly receive a container thereon. For example, a container having a seal can be coupled directly to the adapter, and a portion of the adapter can be configured to puncture the seal upon mating.

As shown in FIGS. 6A-6D, the illustrated adapter 400 has a substantially rounded triangular shape and includes a bottom surface 410 and an upper surface 420. The triangular shape can be defined by a perimeter having first, second, and third sides, with the first side being longer than each of the second and third sides. While the adapter 400 is shown as having a specific form, the adapter 400 can take on a variety of forms. The illustrated form is merely provided to correspond to the shape of the illustrated carriage assembly.

The adapter 400 can have a minor axis B and a major axis A, and the adapter 400 can be substantially symmetrical about the minor axis B. The adapter 400 can include an inlet 424 and outlet 426 that extend through the adapter 400 from the upper surface 420 to the bottom surface 410. The inlet 424 and outlet 426 can be positioned on the adapter 400 such that the inlet 424 and outlet 426 are aligned along the minor axis. In other embodiments, the inlet 424 and outlet 426 can be positioned on the adapter 400 in an offset manner, unaligned along the minor axis. As seen in FIGS. 6A and 6D, the inlet 424 can include an inlet collar 424A disposed on the bottom surface 410 of the adapter 400, defining an opening of the inlet 424. Although the inlet collar 426A is shown in a circular form, the inlet collar 424A can take on a number of shapes, including various geometric shapes, e.g., a triangle, a star, etc., as well as fanciful and/or irregular shapes, e.g., a letter, a logo, etc. In other embodiments, the inlet can be in the form of an opening without any collar.

As shown in FIGS. 6A and 6C, the adapter 400 may include at least one anchor 440 disposed on the bottom surface 410 of the adapter 400. The at least one anchor 440 can extend outwardly from the bottom surface 410 of the adapter 400 and can include a detent 442 to receive a corresponding protrusion in a carriage assembly. The anchor 440 can include a window 444 above the detent 442. The at least one anchor 440 and detent 442 can couple with features of the carriage 120 in order to facilitate coupling of the adapter 400 to the carriage 120. The at least one anchor 440 can take on various other forms as well, and its form may be at least partially dependent upon the placement and form of components on carriage 120. For example, in other aspects the detent can be on the carriage and the anchor can have a projection. The adapter 400 can have two anchors 440 disposed on bottom surface 410, extending downward from opposed ends across the inlet and outlet ports, as seen in FIG. 6D.

As further shown, the adapter 400 can include connection collars 424G, 426G disposed on upper surface 420. One connection collar 424G can define an opening of inlet 424, and the other connection collar 426G can define an opening of outlet 426. The inlet 424 and outlet 426 can each include a flared connection point 424H, 426H. The adapter 400 can include one or more of an inlet valve 424D and an outlet valve 426D, located within the inlet 424 and outlet 426, respectively. Each valve can have a configuration similar to the valves previously described.

FIG. 6E depicts the external container 470. The container 470 can have a variety of shapes and sizes as it is not directly coupled to the carrier 120. The container 470 can include an inlet 474 and an outlet 476. In some embodiments, the container 470 can include one or more of an inlet valve 474D and an outlet valve 476D, located within the inlet 474 and outlet 476, respectively. This can be in addition to or instead of valves 424D, 426D located in the adapter 400.

As seen in FIG. 6F, the adapter 400 may be coupled to the external container 470 via tubing 460. The tubing 460 may be flexible or rigid and provides fluid communication between the adapter 400 and the external container 470. The tubing 460 can comprise two tubes. One tube of tubing 460 may connect the container inlet 474 to the adapter inlet 424, and another tube of tubing 460 may connect the container outlet 476 to the adapter outlet 426. The tubing 460 can be coupled to the adapter 400 by inserting the flared connection points 424H, 426H into the tubes of tubing 460. The tubing 460 may be used to introduce gas into the external container 470. This increases the pressure within the external container 470 and causes additive to exit via the container outlet 476.

While not pictured, the adapter 400 can include any of the features described herein, including collars, protrusions, recessions, etc. to aid in coupling the adapter 400 to the carriage 120.

When the additive container 200 or adapter 400 is properly seated in the carriage assembly 100, a beverage dispensing process can occur using the stored additive. A user can select their beverage preferences, specifying details including volume, carbonation level, additive type, additive amount, and more. When the selections are received by the dispensing system 10, a beverage can be dispensed with the selected characteristics.

If an additive is desired, air or another gas, including carbon dioxide, nitrogen, oxygen, and the like, can be pumped through a gas line and into the interior of the housing 250 through an inlet port in the carriage 120 and through the inlet 224 in the container 200. The resulting increase in pressure within the additive container 200 can cause the outlet valve 226D to open and additive to dispense through the outlet 226 and an outlet port of the carriage 120, into a drink container, such as the drinking glass 26 depicted in FIG. 1 . In embodiments where the additive is a fluid, the additive can be dispensed at a certain dispensing flowrate under a certain pressure.

FIGS. 7A and 7B show another embodiment of cap 500 which can be integrally formed on a container or can be configured to couple to a container. The illustrate cap 500 has a cap base 520 with a single recess 528 having a crescent shape. The single recess 528 may have a sidewall that curves to follow the contour of only the inlet 524, and the outlet 526 may be flush with the lower surface of recess 528. A central pattern 530 may take the form of a partial circle around inlet 524. The single recess 528 may have a crescent or half-moon shape. Protrusions 138 of the carriage 120 may be configured to be inserted into the single crescent recess 528, and the circular central pattern 530 may be configured to be inserted into the central recess 137 of carriage 120.

As explained previously with respect to the carriage 120, although the cap base 520 is described and shown as having certain areas recessed and other areas protruding, cap bases with the opposite features are contemplated herein as well, i.e., all protrusions are recesses and all recesses are protrusions. Further, cap bases are also contemplated that may have only a portion of the features interchanged, such that only one or a few protrusions are recesses and/or only one or a few recesses are protrusions.

FIGS. 8A and 8B depict another embodiment of an additive container 600 having an extra wide housing 650 according to some variations. The extra wide housing 650 can be seen especially in FIG. 8A, and it may include many of the features described herein with respect to other containers. For brevity, these comparable features will not be described again. The housing 650 may have a large width that extends to occupy additional space across one or more carriages 120, allowing the container 200 to store an increased amount of the additive. The housing 650 has a substantially rounded rectangular shape. While the housing 650 is shown as having a specific form, the housing 650 can take on a variety of forms. This rounded rectangular form can include a minor width about a shorter dimension of the housing 650 and a major width about a longer dimension of housing 650.

As shown in FIG. 8B, when seated with a carriage 120, the container can be configured to extend across an entire upper surface of the carriage 120, while still allowing an interface portion of the container to mate with the carriage.
